' Application filed July 19, 1900. Serial No. 24,188. a) model.)

To all whom it may concern:

Be it known that I, CHARLES I. TENNEY, a citizen of the United States,residing at Mason City, in the county of Cerro Gordo and State of Iowa,have invented certain new and useful Improvements in Carburetors; and Ido hereby declare the following to be a full, clear, and exactdescription of the invention, such as will enable others skilled in theart to which it appertains to make and use the same.

This invention relates to apparatus for the production ofilluminating-gas from a liquid hydrocarbon, such as gasolene, and hasfor its object to increase the efficiency of such apparatus and improvethe quality of the product.

The nature of the invention will fully appear from the description andclaims following, reference being had to the accompanying drawings, inwhich Figure l is an ideal section of apparatus embodying my invention.Fig. 2 is a vertical section through the middle of the carbureter, andFig. 3 is a horizontal section of the carbureter below the line a b.

In the drawings, A denotes a cistern or tank supplied with water. B is abell suitably mounted to rise and fall therein, according to the volumeof air within it. In the bottom of the tank is placed a carbureter O,which communicates with the interior of the bell by a stand-pipe D,extending above the surface of the water. By means of a looped pipe Eair is forced into the bell and thence into the carburetor by a suitableblower. (Not shown.)

The details of the carbureter are illustrated in Figs. 2 and 3. G is ashell or case, preferably provided wit-h an inclined top, in the apex ofwhich is attached a pipe F to carry away the gas generated therein. Nearthe top is a horizontal diaphragm O and between this and the bottom arealternating partitions C to give the air passing through the gasolene inthe carbureter a circuitous course,and thus carburize it. The course ofthe air is The air enters the carburetor at pipe.

D', and after traversing all the partitions therein passes into theupper part of the earbureter as gas through a suitable hole G.

Without which it is impossible to produce gas,

of uniform quality.

1 At a suitable distance from the carbureter audits containing-cisternis placed the gasolene-reservoir H. This is provided with a suitablesupply-pipe I, and also with means for drawing out its contents, such asthe forcepump J illustrated. In practice the pump is provided with twosuction-pipes, the pipe K extending to the bottom of the reservoir, soas to draw out the heavier oil settling to the bottom, and a shorterpipe K, terminating some distance above the bottom of the reservoir anddesigned to supply a good and practically uniform quality of gasolene tothe carbureter, or through a return-pipe L, at-

tached at one end to the pump and the other end communicating with thepipe F. Connecting with the pipe L is a Waste-pipe M, provided with asuitable stop-cock M. Stopcocks are also provided at L, K and K withsuitable means for opening and closing the .two latteras, for example,the lift-rods K.

It will be seen that the reservoir H is placed with its bottom below'thelevel ofthe bottom of the tankA and the carbureter thereon, and its tophigher than the top of the carbureter; The pipe F communicates with theupper part of the reservoir. From the bottom of the carburetor a pipe Nleads to the bottom of the reservoir and is provided with a stopcock N,opened and closed by means of a long-stemmed wrench O.

The operation of the apparatus is as follows: The reservoir andcarbureter being empty, the reservoir is first filled with gasolene upto a certain predetermined line corresponding with the desired level inthe carbureter, (the apparatus for gaging this depth not being shown,)the stop-cock N being open. At the desired level the stop-cock is closedand the filling of the reservoir continued as much as may be desired. Asthe gasolene in the carbureter is consumed a new supply is introducedthrough the pipes K, L, and F by means of the pump J or equivalentapparatus. In this Way the carbureter is continually supplied withgasolene of a suitable quality for service, not the very lightest, atthe top of the reservoir, nor the heaviest, which is at the bottom, buta good uniform quality. When after long service the carbureter showssigns of having itself received a deposit at the bottom of unsuitablematter, as is inevitable in all apparatus of this nature, it may bedrained off into the reservoir by opening the stop-cock, the level ofthe gasolene in the reservoir being of course below the bottom of thecarbureter. Thence it may be pumped off through the waste-pipe byclosing the cocks K and L. As the upper portion of the reservoir ishigher than the top of the carbureter an air-space or rather a space forgas is provided in such reservoir, so that as the gasolene is drawn outits place is occupied by inflowing gas and no vacuum is created. So, onthe other hand, when the reservoir is recharged the gas simply flows outof the reservoir to make way for the gasolene poured in.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is-

In a gas-machine, the combination of acarbureter, a gasolene-reservoirlower at the bottom and higher at the top, respectively, than saidcarbureter, a pipe connecting the lower portions of both carbureter andreservoir, a stop-cock for the same, a pipe connecting the upperportions of both carbureter and reservoir, a pump having onesuction-pipe terminating near the bottom of the reservoir and anotherterminating some distance from said bottom, stop'cocks for said pipes, asupply pipe leading from the pump to the carbureter, a waste'pipecommunicating also with said pump, and stop-cocks for both such pipes,

'substautially as and for the purpose set forth.

In testimony whereof I affix my signature in presence of two witnesses.
